def chiller_jaadu(price, fives, ones):

remaining_fives, remaining_ones = fives, ones

fives_required, ones_required = price // 5, price % 5

if fives_required > remaining_fives:

ones_required += 5 * (fives_required - remaining_fives)

remaining_fives = 0

else:

remaining_fives -= fives_required

if ones_required > remaining_ones:

return -1

else:

remaining_ones -= ones_required

return f"Fives: {fives - remaining_fives}\nOnes: {ones - remaining_ones}"

fives, ones = int(input("five coins: ")), int(input("one coins: "))

print(chiller_jaadu((price := float(input("price: "))), fives, ones))
